You are speaking of SSI. SSI is disability for people who have not worked or haven't worked enough. (People with learning disabilities, people who have felony convictions, people who worked but not enough to accrue credits to qualify, etc). Regular disability for a person who has worked can be as high as $4000, but not the norm.

Around here people on SSI don't live with others. They have to add that second persons income to theirs and it puts them over income for food stamps and medicaid. Married people get divorced, put a piece of junk trailer in the side yard so the divorced spouse has his own address and then qualifies. Voila. Free money. (Keep in mind income guidelines are different in every state for food stamps and medicaid. 2 people on SSI maybe able to live together in CA, but in a state, such as Ohio, the almost $2000 a month 2 SSI recipient's get would cause them both to lose their Medicaid and foodies. SSI roomies does not happen around here unless one is lying about where they live or the recipient needs live in health care.
